It *might*, by some hapless master's student regurgitating the
proof. But that doesn't mean it should be encoded. It's an ad hoc
symbol, local to a particular series of papers (in so far as there is
a customary symbol, it's \sigma, but in that series of papers I needed
\sigma for another purpose), and within those papers, local to the
proof of particular theorems.
Anybody who reads the papers with understanding will realize that, and
therefore feel free to use any other symbol that is convenient to
them, if they don't feel like putting together a mu-nu symbol.
Once, I used $\mu \atop \nu$ (a small mu on top of a small nu) instead
-- that's in print too, in a very expensive book! Would you want to
encode that too?

If you're looking for more characters to encode, I'd rather see
COMBINING DOUBLE TILDE BELOW
which is used in Ladefoged and Maddieson, The Sounds of the World's
Language, to denote the strident vowels of Khoisan languages, and
which I therefore use in my work too.
